From U.S. News:
If you want to know what Georgia Tech University is doing to make their drones fly, you better have deep pockets. Georgia Tech is one of many public agencies that are asking for thousands of dollars in order to release document related to their research and testing of drones.
According to open government nonprofit organization MuckRock, which, along with the Electronic Frontier Foundation, is compiling a “drone census” of public agencies that are using unmanned aerial vehicles, many agencies have been less than forthcoming with details of their drone use.
